BACKGROUND

A craft knife is a cutting tool that is commonly used in a variety ofapplications. Standard craft knives handles are generally configured tohold cutting blades by engaging with holes or notches formed in thecutting blade. In certain circumstances, it may not be possible tomanufacture a cutting blade that has the appropriate holes or notchesdue to design limitations of particular materials. As an illustrativeexample, forming a hole or notch in a ceramic cutting blade compromisesthe strength of the ceramic cutting blade and increases themanufacturing costs. If the craft knife handle does not engage with anotch or hole in the cutting blade, then the cutting blade may not besecured sufficiently so as to prevent unwanted movement or shifting ofthe cutting blade within the craft knife handle.

DETAILED SPECIFICATION

The present invention generally relates to craft knives. Specifically,embodiments of the present invention relate to a craft knife handle thatis configured to securely hold a cutting blade without the need toengage with a hole or notch in the cutting blade. Embodiments of thecraft knife handle further include a no-roll design and safety cap.

According to an embodiment of the present invention, the craft knifehandle described herein primarily comprises a handle body and a handlecollar. In some embodiments, the craft knife handle further comprises acutting blade and a safety cap. Certain embodiments of the craft knifehandle may include fewer components or additional components dependingon the utilization and purpose for the craft knife handle. Embodimentsof the craft knife handle may be formed in a variety of designs andoptionally configured with any combination of components with departingfrom the spirit and scope of the invention.

According to an embodiment of the present invention, the handle body ofthe craft knife handle is a single, continuously formed unit. In apreferred embodiment, the handle body may be primarily cylindrical inshape and comprises a front segment configured to receive cutting blade,a middle segment configured to engage with the handle collar, and a rearsegment formed with a no-roll flat facet. In the preferred embodiment,the front segment is formed with a blade slot that begins as a V-shapednotch in the front tip of the handle body and extends as a slot alongthe length the front segment. The middle segment includes a threadedportion that defines the front boundary of the middle segment is adaptedto engage with a corresponding threaded portion on the inside of thehandle collar. The rear segment is configured with at least one flatfacet that prevents the craft knife handle from rolling. In thepreferred embodiment, the front segment has a smaller diameter relativeto the middle segment and the middle segment has a smaller diameterrelative to the rear segment. One of ordinary skill in the art wouldappreciate that there are many suitable designs for a craft knifehandle, and embodiments of the present invention are contemplated totake advantage of any such design.

According to an embodiment of the present invention, a blade slot isformed in the front segment of the craft knife handle. In a preferredembodiment, the blade slot is an opening formed continuously from thetop to the bottom of the front segment and passes through thelongitudinal axis of the front segment. The blade slot begins as aV-shaped notch at the tip of the front segment, continues through thefront segment and terminates at a blade slot recess that is formed inthe front of the middle segment of the craft knife handle. In thepreferred embodiment, the width and height of the blade slot aresufficient to the accommodate the thickness and height of the desiredcutting blade, while the length of the blade slot is sufficient to allowthe rear portion of the cutting blade to sit in the blade slot recessand the front portion of the cutting blade to extend beyond the fronttip of the craft knife handle.

According to an embodiment of the present invention, a blade slot recessis formed in the front of the middle segment of the craft knife handle.In a preferred embodiment, the blade slot recess is a notch,indentation, groove, or similar depression that extends into the middlesegment of the craft knife handle and is configured to provide afriction fit with the rear portion of the cutting blade by engaging withthe rear edges of the cutting blade. In the preferred embodiment, theblade slot recess begins at the point where the threading begins on themiddle segment of the craft knife handle. As the blade slot recessextends into the craft knife handle, the blade slot recess initially hasthe same height as the rest of the blade slot, but begins to taper downin height from both the top and bottom of the blade slot recess. Thetaper of the blade slot recess may appear as two ridges or bumps, withone on the top side of the blade slot recess and another on the bottom.The tapering of the blade slot recess enables a tighter fit between thecraft knife handle and the cutting blade, as the tapered blade slotrecess compensates for various manufacturing tolerances in cuttingblades, as well as the craft knife handle. When a cutting blade isinserted into the blade slot in the front segment of the craft knifehandle, the rear portion of the cutting blade is eventually pushed intothe blade slot recess where the tapering height of the blade slot recesscauses the blade slot recess to firmly grip the edges of the cuttingblade. By firmly gripping the edges of the cutting blade, the blade slotrecess reduces or eliminates blade wiggle or shifting that can resultfrom manufacturing tolerance in the cutting blade, in particularvertical wiggle that is caused by tolerances in the height of thecutting blade.

According to an embodiment of the present invention, the middle segmentof the handle body is configured with a collar engagement means thatenables the handle body to reversibly engage with the handle collar. Ina preferred embodiment, the collar engagement means on the middlesegment is formed as a threaded portion that reversibly engages with acorresponding threaded portion on the interior of the handle collar. Thethreaded portion of the handle body allows the handle collar to betightened onto the handle body to secure the cutting blade within theblade slot.

According to an embodiment of the present invention, the rear segment ofthe handle body is formed with at least one flat facet to preventunwanted rolling of the craft knife handle. In a preferred embodiment,the rear segment is formed with a raised flat portion that extends offof the otherwise generally cylindrical shape of the handle body. In thepreferred embodiment, the raised flat portion prevents unwanted rollingof the craft knife handle when the craft knife handle is placed on asurface. Additionally, the rear segment also forms the rear tip of thecraft knife handle. The rear tip of the craft knife handle may beconfigured to receive the safety cap of the craft knife handle, with thesafety cap being pushed onto and over the rear tip of the handle bodyand being secured with a friction fit.

According to an embodiment of the present invention, the handle collarof the craft knife handle may be primarily tubular in shape and isconfigured to reversibly engage with the handle body of the craft knifehandle, as well as being the portion of the craft knife handle by whichcraft knife handle is generally held while the user is making cuts. In apreferred embodiment, the handle collar is configured as a tube with ahandle body engagement means formed on at least a portion of theinterior of the handle collar. In preferred embodiment, the handle bodyengagement means is configured to engage with the collar engagementmeans on the handle body. The handle body engagement means of the handlecollar is preferably formed as a threaded portion on the interior of thehandle collar. In the preferred embodiment, the threaded portion of thehandle collar is configured to engage with a corresponding threadedportion on the collar engagement means of the handle body. When thehandle collar is threaded onto the handle body, the handle collar causesthe blade slot of the handle body to tighten against and firmly grip thefront and rear faces of the cutting blade so that the cutting blade isheld securely within the blade slot in the front segment of the handlebody. Conversely, as the handle collar is loosened from the handle body,the cutting blade can be removed or replaced. In the preferredembodiment, the front tip of the handle collar has a slightly smallerdiameter than the rest of the interior of the handle collar. Theexterior diameter of the handle collar is smallest at the front tip ofthe handle collar and gradually increases to the full diameter of thehandle collar, leaving most of the handle collar to be the largerdiameter. The interior diameter of the handle collar begins with aslightly small diameter for a short segment, and then graduallyincreases to the full interior diameter roughly in parallel with theoutside diameter, thereby creating a handle collar that has front tipthat has slightly smaller diameter relative to the rest of the handlecollar. In the preferred embodiment, the short smaller interior diametersegment of the handle collar is connected to the larger diameterremainder of the handle collar by a sloped segment. By changing diametervia a sloped segment, as opposed to in a stepped fashion, the handlecollar of the craft knife handle generates an increased gripping forceon the first segment of the handle body, without damaging the handlebody. Additionally, the handle collar may be weighted and made from amaterial such as copper to provide a weighted balance to the craft knifehandle. Furthermore, the handle collar may be textured or otherwiseconfigured with an anti-slip grip to allow for a secure grip and precisecontrol of the craft knife handle. One of ordinary skill in the artwould appreciate that there are many suitable designs for a handlecollar of a craft knife, and embodiments of the present invention arecontemplated for use with any such design.

According to an embodiment of the present invention, the blades used inthe craft knife handle of the present invention may be constructed froma ceramic material that is capable of withstanding extended use withoutbecoming dull or unusable. Ceramic materials appropriate for suchconstruction include, but are not limited to, Zirconium Oxide. Incertain cases, manufacturing costs and other design limitations of blademade from ceramic materials require that the blades be formed withoutand holes or notches, which can weaken the strength of a ceramic blade.However, the handle collar and handle body of the craft knife handle ofthe present invention are adapted to securely hold a cutting bladewithout the need to engage with a hole or notch formed in the cuttingblade. One of ordinary skill in the art would appreciate that there arenumerous ceramic materials that could be utilized with embodiments ofthe present invention. Alternatively, embodiments of the presentinvention may be used with standard craft knife blades.

According to an embodiment of the present invention, the blades used inthe craft knife may contain rounded tips to reduce the chance of injury.

According to an embodiment of the present invention, the craft knifehandle may further include a safety cap that is configured to reversiblyattach to both the front tip and the rear tip of the craft knife handlevia friction fit between the safety cap and the craft knife handle. Inparticular, the safety cap engages with the front tip of the craft knifehandle by sliding over handle collar at the front segment of the handlebody and engages with the rear tip of the craft knife handle by slidingover the rear segment of the handle body. In a preferred embodiment, thecraft knife handle may be formed with at least one flat facet to providefor a no-roll design. When the craft knife handle is not being used, thesafety cap can be pushed onto and over the front tip of the craft knifehandle, thereby covering the cutting blade to improve safety and preventwear on the cutting blade. When the craft knife handle is being used,the safety cap can be secured to the rear of the craft knife handle,thereby keeping the safety cap together with the craft knife handle andreducing the chance the safety cap becomes loss or otherwise misplacedfrom the craft knife handle. One of ordinary skill in the art wouldappreciate that there are many suitable designs for a safety cap, andembodiments of the present invention are contemplated for to takeadvantage of any such design.
